Product Introduction
Introducing our exceptional 1x7 structure unbonded prestressed steel strand, crafted to precision in dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. This meticulously engineered marvel features a protective coating of anti-corrosion grease and is encased in a robust sheath, making it an ideal selection for water conservancy and hydro-power projects. With the escalating demand for sustainable energy solutions, our steel strands play a crucial role in constructing towering wind power towers, soaring to heights surpassing 120 meters. These concrete towers leverage external prestressing technology, utilizing our unbonded prestressed steel strand, celebrated for its unparalleled corrosion and fatigue resistance. This superiority not only fortifies wind resistance but also significantly prolongs the towers' operational lifespan.
Our product design is anchored on the prestigious JG/T 161-2016 standard for Unbonded Prestressed Steel Strand. We've revolutionized the design framework to streamline the testing process of the sheath's tensile properties, thereby enhancing its practical usability and facilitating theenhancement of sheath performance. This innovation not only rigorously standardizes the sheath quality but also significantly elevates the safety and overall quality of prestigious engineering projects.
Product Characteristics
Our unbonded steel strand for wind power concrete towers stands out with an outer cable specifically engineered for superior performance. The sheath's thickness and grease composition are adaptable, tailored to fulfill distinct user requirements. The sheath's surface is flawlessly dense and smooth, allowing the steel strand's outline to be distinct. It adheres to strict quality standards, ensuring the absence of air holes, mechanical damage, cracks, or noticeable wrinkles.
Product Application
The range of application domains spans Wind Power and Water Conservancy,
as well as Hydro-power Stations.
The South-North Water Transfer Project,
River Channels, and other nationally prioritized water conservancy and hydropower projects.
